 Circles/418786: If a circle has a radius of 6inches what is it's approximate circumference. 1 solutions Answer 293005 by praseenakos@yahoo.com(507)   on 2011-03-07 15:58:19 (Show Source): You can put this solution on YOUR website!circumference = circumference = circumference = square inches
 Rectangles/418780: the area of a rectangle is 56 square feet. its lenght is 10 feet longer than the width. find the lenght and width?1 solutions Answer 293003 by praseenakos@yahoo.com(507)   on 2011-03-07 15:55:09 (Show Source): You can put this solution on YOUR website!width = x feet length = x + 10 feet area = length x width 56 = x(x+18) ==> x + 14 = 0 or x-4 = 0 ==> x = -14 or x = 4 since length and width cannot be a negative number, you can ignore the negative value u got for x ==> width = 4 feet so length = 4 + 10 = 14 feet

 Geometry_Word_Problems/417178: The length of a rectangule is 2 cm more than 5 times the width, the perimeter is 196 cm. find the width and length 1 solutions Answer 292138 by praseenakos@yahoo.com(507)   on 2011-03-03 20:45:57 (Show Source): You can put this solution on YOUR website!let the width = x length = x + 2 Perimeter = 196 2(length+ width ) = 196 width = 48 so length = 48+2 = 50
 Triangles/417242: The sum of the measures of the three angles of a triangle is 180 degrees. Find the three angles if two angles are the same and the third is 60 degrees more than the other two.1 solutions Answer 292136 by praseenakos@yahoo.com(507)   on 2011-03-03 20:40:28 (Show Source): You can put this solution on YOUR website!let the angles are, x, x, and (x+60) ==> x + x + x + 60 = 180 ==> 3x + 60 = 180 ==> 3x + 60 - 60 = 180 -60 ==> 3x = 120 ==> ==> x = 40 so the angles are 40,40, and 100
